SMARCA4 mutations are common in Medulloblastoma but not much is understood about its pathobiology. In this study we prepared SMARCA4 knockdown models using a Group 3 medulloblastoma cell line called HDMB03 and investigated the proteomic changes. Nuclear enrichment was performed using hypertonic and hypotonic buffers. The nuclear enriched fractions were analysed on LC-MS/MS.
